## Analysis

THE ACFT BEGAN TO LOSE POWER AT 700 FT MSL DURING CLIMBOUT. THE PILOT TRIED THE BOOST PUMPS AND WAS ABLE TO REGAIN SOME POWER MOMENTARILY. WHEN ALL POWER WAS LOST THE PILOT WAS FORCED TO LAND SHORT OF THE AIRPORT ON A FROZEN RIVER. THE ROUGH ICE SHEARED THE NOSE GEAR DURING ROLL-OUT. THE PILOT STATED IN AN INTERVIEW THAT HE WAS UNAWARE OF TRAPPED WATER IN FUEL TANKS AND HE DID NOT DRAIN THE FUEL SUMPS DURING PRE-FLIGHT.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power(total) - nonmechanical, takeoff - initial climb
  - fuel system,tank - inadequate (cause)
  - acft/equip,inadequate design, production/design personnel (cause)
  - fluid,fuel - water (cause)
  - fluid,fuel - ice (cause)
  - aircraft preflight - inadequate, pilot in command (cause)
- Forced landing, landing - flare/touchdown
- Nose gear collapsed, landing - roll
  - landing gear,nose gear assembly - overload (contributing factor)

## Other investigations on N7389U (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
